Severe WX Severe Threat 25 March 2021

[TH2002]

From what I heard from a guy on Twitter he said debris from the Newnan tornado was lofted over 15,000 feet into the air and that would be consistent with an EF3 tornado. However, of course Newnan was rated an EF4. I am not sure how debris being lofted into the air necessarily has anything to do with the intensity but I would think there would be at least some correlation.

I would also believe there is a correlation, though evidently using the height of lofted debris is a very hit-or-miss way to rate tornadoes.

I don’t mean to be rude, but I think it’s pretty obvious from what I’ve seen that ef5 damage didn’t occur. Even multiple ef4’s feel like a stretch imo. However, I’m not a professional doing surveys.

 

[pohnpei]

Newnan based on radar DEFINANTLY had EF5 potential

Based on radar?EF5?

A huge pet peeve for me is for guesstimated ratings from non-survey mets via looking at pics!!

The VROT/TDS height chart usually performs very well; I think the discrepancy lies in how close the tornado was to the radar site and the amount of debris which apparently hampers VROT resolution slightly. Either way I think it was within the margin of error for low EF4. Pretty rare to have a tornado rated STRONGER than suggested on the chart

That is what I read last night. Thank you for finding it.

I thought some tornadoes such as the Tuscaloosa tornado from 4/27 and the Bassfield tornado from last Easter lofted debris over 30,000 feet into air.

I’m honestly shocked they went with EF4. FCC is pretty conservative with their ratings. I was almost certain they’d go with high EF3. Maybe they’re not as dismissive and conservative these days.

Me too. Based on the aerial video, I mean, the contextual damage overall didn't highly indicate of EF4 level strength with very little debarking or vehicle damage can see. But if the house did have anchor system, it is likely appropriate.

The velocities were very high at one point

Oops i meant to respond to pohnpei sorry!! anyways it looked like it had violent very violent potential on radar

It looks like some of the debris was lofted 23,000 feet into the air according to that chart so it was probably capable of even stronger damage.

 

[speedbump305]

I think the Brent and Newnan tornadoes were probably capable of EF5 damage somewhere along their paths. The radar return from the debris ball on both tornadoes was absolutely scary.

Very correct. The radar velocities may have actually been higher than bassfield

We do need to remember that surveys are still going and probably will be finished tomorrow afternoon. and it really pains me to say... but newnan wasn’t the only place that got hit besides franklin.

Precisely why I prefer the F Scale vs. the EF Scale.

In my opinion, The F scale had a lot of tornadoes that shouldn’t have been rated as such. that’s why i prefer the EF. but both have their wormys

LMAO wormys, anyway i meant to say wrongs

It just didn't higher than Bassfield or Greensboro and I have to remind that the caculatation of radar based EF scale rating have to consider the Height of the scan which was pretty low for Newnan tornado.

holy moly- dang. it did look that way at first. i actually think i got confused for the Newnan tornado over the brent tornado sorry!!
